Country:  | It wasn't ready in time though. And with most of the revolutionary Italian designs of the 30s, it would have probably broken down on the day.

| Well it is a fact that the MC72 was not ready in time for the Schneider cup, it is a fact that (like all racing airplanes, cars and trucks) was easy to broke and it is a fact that the MC 72 still holds the world speed record for prop seaplanes with 709 kmh.
I have some info in an old magazine, if I find it I will post some more details.

| If the rules had forced all the racers to use the same fuel I don't think that it would have been so easy for British engineers and pilots.
Supermarine S6 got a speed record of 655 Km/ h during the edition of september 1931 , with 2783 HP and a maximum pressure of 2.45 BARs from the supercharger and a M.E.P of 20 BARs (!).
Such performances would have been impossible for overheating and premature detonation troubles in the cylinders without a special kind of fuel projected by chemical engineer F.R Banks of Associated Ethyl.
A special fuel which could be only formally called "gasoline" since neither a drop of gasoline was in the tanks of Supermarine S6: 60 % Methilic alcohol, 30% benzylic alcohol, 10 % acethic acid for a fast evaporation in the carburettor to cool the air/fuel mixture and a sufficiently good caloric power to limit the consumption, + 11.1 parts/1000 of TEL to prevent premature detonation.
In Italy nobody knew anything about special fuels in 1930.MC 72 could express the superlative power of 3100 HP and the consequent speed record in few months without significative breakdowns or other troubles, thanks to the consulence of engineer Banks after the expiration of his agreement with Rolls-Royce.The fuel employed for the record was not as "exotic" as the one used by Rolls-royce: 55% gasoline, 23% ethilic alcohol, 22% benzylic alcohol + 1.5 parts/ 1000 of TEL.It was less polluting as well!
Italians had to project by themselves the first in-line tandem-style twin engine in the world, a reliable aeronautical supercharger ,a new fuel for racing purpose.....starting from zero, with their poor resources they challenged a giant as British Empire.Just to face such challenge was a success in itself....

This is the best prove of the fact #1: MC 72 was not ready on time...
2 - About 'trickyness' of the racers.
At least two MC 72 crashed during the trials for the 1931 edition, with the death of pilots Monti and Bellini.
In the same edition the British suffered the loss of pilots E.Hope and G.L Brinton, while pilots Orlebar and Stainforth survived the crash of their machines (I have no reliable info if the machine was the S6 B or another competitor)
It seems enough to confirm fact # 2
3 - This is easy, just make a google search !
The speed record of 709,202 Kmh (with a best lap of over 711) obtained on Oct. 23, 1934 is still unsurpassed for prop driven seaplanes.
5 years later (March 1939) the record for prop driven planes was taken by the Heinkel He100 (746,450) , and in August 1961 the jet engined Beriev M10 took the record for seaplanes with 912 Kmh.
But no other 'otto' seaplane was ever faster than the MC 72.

Country: | Well Ollie I went up the science museum and got some shots of the S6B but as usual I'm as lucky as a one legged man at an arse kicking contest the plane is being restored. It had a bleeding great vacuum cleaner stood in front of it,the Schnieder Trophy is away for cleaning and the plane has been moved from where it used to stand so getting a shot in what was really low light conditions was a total bugger. So Im really sorry for the crappy shots Ollie.

Country: | Yes. Nice pics Lee, it doesn't look in too good a shape which is not nice to see but at least it is being restored.

| Thank you for the photos.It is a shame such a famous aeroplane is in such a mess. What are they planning with that vacum cleaner? | |
